>Description:

extend.texi contains documentation of preprocessor extensions -
GNU-style macro varargs, and the support of C++ comments in gnu89
(default) mode.  The documentation of macro varargs seems to be out of
date.

>How-To-Repeat:

Read both the GCC and CPP manuals and find them to be inconsistent.

>Fix:

Add a section to the cpp.texi manual summarising the non-deprecated
extensions in one place (with updated documentation of the acceptance
of C++ comments except when in strict C89 or traditional mode), and
point to there from extend.texi, removing the existing cpp-related
items from extend.texi.
